Hi Max,

I've left the AvailableAtLoopEntry as conditionals and not asserts, as it seems safer at the moment. Things done:

- added more tests
- renamed the argument
- added an assert for LatchBrExit == 0
- exit early, only checking once, that AvailableAtLoopEntry is true
- added debug messages into the new function
